TO ALL WHOMIT MAY CONOERN:

Be it known that we, JOSHUA HARRISON, of Brooklyn, inthe cpunty of Kings, and State of New York, and GEORGE W. HARRIS, of thc city, county, and State of New York, liaveinvented certain new and useful mprovcments in Clothesf'Wringers; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The object of our invention is to produce or furnish a olothes-wringer which shall at the same time be cheaper, more durable, and easier in its operation than other first-class machines now in use; in which the passagebetween the rolls of an article of more than usual thickness, requiring more than the usual amount of power to be applied to turn the rolls, will cause the fastenings which secure thev machine to the tub to hold more rmly, and in which the rolls fallapart when the machine isremoved from the tub, thereby preventing injury to the rollsby their being left screwed tightly together 'after having beenheated by use.

The devices and combinations of parts by which these results are secured, and which constitute our invention, are- First, the combination in a clothes-wrmger of one cork and one rubber roll, by which the machine is rendered cheaper and more durableA than similarmachines withtwo rubber rolls, and as durable and much easier in'its operation than a machine in which two cork rolls are employed. v

Second, the'combination with the rubber roll and cork roll of a long, curved, or elliptic spring, and a bar across the top of 'the machine, against\wl1ich the middle of said spring rests, lby which the upper roll is pressed down against the clothes operated upon, and which yields to allow a thick article to pass between the rolls.

' Third, the combination with the rubber roll, cork roll, spring, and bar, of bent levershung at one `end to the` frame of the machine, and rbearing against the tub at the other end; the lower roll being hung at the angle in such a manner that any downward pressure on the lower roll will causethe lower end oi'said bent lever to bear more firmly againgt the tub; and so that when the machine is removed from the tub, the said lower roll may drop down sufficiently to remove it from contact with the upper roll. For this purpose the slots in the framein which the journal-boxes which support the rollsplay are so arranged that when both rolls are at their lowest point, as they are when the machine is not in use,v'there shall be a slight interval or opening between the fac-es o'f the rolls. By this construction the fastenings which-secure the wringer to the tub hold more securely by aid of the bent levers when it becomes necessary'to apply extra power to drivethe rolls; and when the machine is removed from the tub the rolls fall apart, and there is no danger of one of them becoming iiattened by being screwed tightly against the other, as frequently happens with machines heretofore used.

By means of the fastenings shown, the wringer `may be secured to a round or square tub with equalusecurity' and facility, thus increasing the range of usefulness of e-ach'machine without adding to its cost. In the accompanying dawings- Figure'l is a side elevation of my improved wringer.

Figure 2 is an end elcvratiouof the same. i

Figure 3 is a vertical cross-section through the centre.

AV and B are the end pieces of the frame; O is a rubber roll, and arcork roll; is the top bar of the frame, againstfwhich the spring F, theends of which bear on the journal-boxes a a of the roller C, and press it dow-n, reacts. GrV 4is another rod or bar which connects ther end pieces A and B at or near their centres, and completes the frame. The end pieces A and B have each two slots in their upper ends, the -upper slots being for the journal-boxes a ato work in, and the lower ones for the journal-boxes b b to work The lower ends of these slots are just far enough apart so that when the journalboxes a aand b b rest in the lower ends of their respective slots the surfaces of the rolls are just removed from contact with each other. The lower ends of the end pieces Av and B are forked so as to enable them to grasp the tub or'other article for containingV the clothes; and one of the forks of each end piece is supplied with a set-screw, L, by which the wringer'is screwed to the tub. H' and I are the bent levers hung to the rod G at their upper ends, and bearing against the tub at or near their lower ends. At the. elbow or angle of these bent levers, seats or bearings b are provided for the shaft K to work in. Theseseats or bearings b, when the machine, is-not in use, rest in the bottom of the lower employed.

slots -in the end pieces A andB of the frame. When the machine isplaced'on the tub and the screwsL tightened, the lower ends of the bent'levers H and I are thrown out, thus raising the roll D, which in turn presses up the roll C, the spring F yielding suiciently for vthat purpose. 5 A

I The machine being now ready for use,lthe articles to be wrung are successivelyr introduced in theusual manner between the rolls, and the lower roll'turned by a suitable crank on the shaft K,which forces or'draws the clothes through the machine and eX-presses the water. f When 4the thicker portions of the articles pass between the rolls, 'the rolll C is pushed upward, the spring F yielding for that purpose, andthe pressure offthe spring F downward ,upon the roll C is transinitted through the clothes and roller D to the bent levers H and Ly causing their lower ends to press more firmly against the tub'. On rerndving the machine from the tub, the

pressure kon the lower endsof the bent levers H and I is removed, andthe lower roll is `then free to drop down.

and free itself` from contact with the upperroll, whereby any danger of the rubber roll becoming permanently flattened by continued pressure after being heated by use is avoided. i By the use of 'the cork. roll as the drivingroll there is no longer anyy necessity nor advantage in the use-of cogor toothed wheels t connect the rol-ls, as thecork roll is-'sulliciently strong and durable to sustain the strain to which it is subjected, and the lower roll is the one which usually gives way or becomes injured where two rubber rolls without toothed gearing are We claim as our inventionv g 1. The combination in a-clothes-wringer of alcork roll. and a rubber roll, substantially as and for the .p urpose setforth.

2. The'combination, with the cork roll D, and rubber roll C, in a clothes-wringer, of the spring F and bar E, 'substantially as set forth. l

3. The combination, with the end pieces A and B forked at their lower ends, therolls C and D, and the spring F, of the bent levers H and the said bent levers being so constructed and arranged as to4 accomplish the results set forth, substantially as hereinabove specified.
